Question 1

The hammer,anvil,and stirrup are three tiny bones that transmit vibrations to the

Accepted Answer

The hammer, anvil, and stirrup are located in the middle ear and work together to transmit and amplify sound waves to the oval window, which is the beginning of the inner ear. From there, vibrations are transmitted to the cochlea, which is responsible for converting sound waves into neural messages that are sent to the brain.

Question 2

The olfactory receptors are activated by

Accepted Answer

Olfactory receptors are specifically activated by odorant molecules, which bind to the receptors and generate an electrical signal that travels to the brain to identify different smells.

Question 3

Damage to the basilar membrane is most likely to affect which sense?

Accepted Answer

The basilar membrane is a key structure within the cochlea of the inner ear, which is responsible for processing auditory information (sound waves). Therefore, damage to the basilar membrane is most likely to affect the sense of hearing, or audition.

Question 4

During the months when there is a large amount of pollen in the air,your hay fever severely affects your sense of smell. At the same time your food all seems to taste the same. This illustrates the importance of

Accepted Answer

This scenario illustrates sensory interaction, the principle that one sense may influence another, as when the loss of smell (due to hay fever) affects the sense of taste.

Question 5

Pleasant memories are most likely to be evoked by exposure to

Accepted Answer

Fragrant odors have a strong association with memory and can evoke pleasant memories because the olfactory bulb is part of the brain's limbic system, which is involved in the processing of emotions and memory. Bright colors, soft touches, and loud sounds are not as strongly associated with memory recall.

Question 6

Touching side-by-side cold and pressure spots triggers a sense of

Accepted Answer

When cold and pressure spots on the skin are stimulated simultaneously, the brain interprets this combination as the sensation of wetness, even if the skin is not actually wet. This is because there is no specific receptor for wetness; instead, our brain interprets the combination of cold and pressure signals as being wet.

Question 7

The sensory experience of bending one's knees or raising one's arms exemplifies

Accepted Answer

Kinesthesis refers to our body's sense of movement and position. Bending one's knees or raising one's arms requires the use of kinesthetic sensors in the muscles, tendons, and joints. The other options are not relevant to this particular sensory experience.

Question 8

A drink's strawberry odor enhances our perception of its sweetness. This best illustrates

Accepted Answer

Sensory interaction refers to the principle that one sense may influence another, as when the smell of food influences its taste. In this case, the strawberry odor enhances the perception of sweetness, illustrating sensory interaction.

Question 9

Receptor cells for the vestibular sense send messages to the

Accepted Answer

Receptor cells for the vestibular sense, which is responsible for our sense of balance and spatial orientation, send messages directly to the cerebellum. The cerebellum is involved in coordinating movement and maintaining balance, making it the most appropriate choice for receiving these messages.

Question 10

Alex tickles his brother by stroking adjacent ________ spots on his skin.

Accepted Answer

Tickling involves stimulating the nerves that respond to pressure, so the best choice is A) pressure spots. The other options, warmth, cold, and pain, do not relate to the sensation of tickling.

Question 11

The rubber-hand illusion best illustrates

Accepted Answer

The rubber-hand illusion illustrates sensory interaction, as it involves the integration of visual, tactile, and proprioceptive information to create the illusion that a rubber hand is part of one's own body.

Question 12

Explain why both top-down and bottom-up processing are emphasized by those who take a biopsychosocial approach to understanding pain and pain control.

Accepted Answer

The answer of Explain why both top-down and bottom-up processing...

Question 13

Receptor cells for our sense of ________ reproduce themselves every week or two.

Accepted Answer

Taste receptor cells have a high turnover rate and regenerate approximately every 1 to 2 weeks.

Question 14

The sense of smell is known as

Accepted Answer

The sense of smell is scientifically known as olfaction.

Question 15

According to the gate-control theory,a back massage would most likely reduce your physical aches and pains by causing the

Accepted Answer

The gate-control theory of pain suggests that non-painful input closes the "gates" to painful input, which prevents pain sensation from traveling to the central nervous system. Therefore, a back massage would likely reduce physical aches and pains by activating certain nerve fibers in the spinal cord that block or reduce the transmission of pain signals to the brain.

Question 16

Sense perception cells that project antennalike hairs are located within

Accepted Answer

Taste buds contain sense perception cells that project antennalike hairs to interact with taste stimuli, allowing us to perceive different tastes.

Question 17

Information from the taste buds travels to an area of the

Accepted Answer

Information from the taste buds travels to the temporal lobe, which is responsible for processing auditory information as well as some aspects of language and visual perception. It includes the primary auditory cortex, which receives signals from the ears, and the hippocampus, which is important for memory formation.

Question 18

Which of the following would play a role in quickly alerting you to a gas leak in your home?

Accepted Answer

Olfactory receptors are responsible for detecting odors, including the smell of gas, which is why they would alert you to a gas leak in your home.

Question 19

The McGurk effect best illustrates

Accepted Answer

The McGurk effect illustrates sensory interaction, as it demonstrates how our perceptions can change based on the integration of visual and auditory information.

Question 20

Which of the following senses is best described as a chemical sense?

Accepted Answer

Smell is best described as a chemical sense because it relies on the detection of chemicals (odorants) in the air that are processed by the olfactory system in the nose. The other senses listed (kinesthesis, audition, and the vestibular sense) are not primarily dependent on the detection of chemicals.
